Note: The May 11, 18, and 25 (i. e., the twenty-fourth through twenty-sixth)
instalments were not illustrated, perhaps because Harper's was providing
extensive pictorial coverage of the Civil War, depicting camps, fortresses, and battles--e. g., "Camp Curtin, Near Harrisburg, Pennsylvania, a Rendezvous of the Pennsylvania Volunteers.--[Sketched by Jasper Green, Esq.]" on page 301 takes up three of the four columns, the fourth being the start of Chapter 38 of Great Expectations. A Civil War scene also occupies the space that might have been devoted to McLenan illustrations on p. 318.
